What is wrong with my sql statment

I am trying to create a search using sql statement and I want the result to show up in the same page just below the searchform. But I keep getting the following error everytime I try to search for a number.
Microsoft JET Database Engine error '80040e10'
No value given for one or more required parameters.
/search-form2.asp, line 41

Sorry, I somtimes post in multiple forums hoping to widen the search for an answer.

I have tried to hardcode a number into the sql statement ("SELECT * FROM tblkunder WHERE OrgNr LIKE 990 362 084")which gives me the following error: Syntax error (missing operator) in query expression 'OrgNr LIKE 990 362 084'.

I can see in the URI that ?search=990+362+084 so I guess it is populating.

It's been several years since I worked with asp and sql so I am very, very rusty and I really need som help.

I thought that Org-nr could give me problems so I renamed it to OrgNr. I also renamed the database to dbKunder and the table to tblKunder but no luck.
